SWITCH-BAR ATTACH M ENT.

SPECIFICATION forming part of Letters Patent No.'739,441, dated September 22, 1903. Application filed June 26, 1903. Serial No. 163,166- (Nomodel-l 1'0 all whom it may concern:

Be it known that I, CHARLES PARTINGTON, a citizen of the United States, residing at Newport, in the county of Campbell and State of Keutucky,have invented certain new and useful Improvements in Switch Bar Attachments, of which the following isa specification.

The object of my invention is to provide a strong and more durable bracket for supporting a tie-bar and connecting it to the switchrail, all of which will be fully set forth in the description of the accompanying drawings, forming a part of this specification, in which- Figure 1 is a plan view of a blank. Fig. 2 is a side elevation of the bracket in position for use. Fig. 3 is a front elevation of the bracket. Fig. 4 is a perspective view-of the inner face of the bracket.

1 represents'a main rail; 2, aswitch-rail; 3, a tie-bar or a switch-bar; 4., the bracket for rigidly connecting the tie-bar to the switchrail; 6, the bolts for fastening the brackets to the switch-rail; 7, a bolt for connecting the tie-bar to the bracket.

The bracket is formedfrom a blank shown in Fig. 1 into the form shown in Figs. 3 and 4. It is provided with a flange a, a neck I),

and a hollow shank c.

01 represents the orifice pierced in the back of the shank through which the tie-bar is inserted.

6 represents a recess formed in the neck of the flange which abuts against the outer edge of the switch-rail flange.

g represents curved oval-shaped flanges curving from the recess 6 backward and downward to the end of the shank c, forming a strong support or brace for the shank and enabling it to Withstand the strains and thrusts imparted to the s'witch-rail through the bracket.

By making the bracket from a rectangular blank and forming the curved flanges g as a continuous connection of the shank to the body of the brace the same amount of metal is employed in all sections of the brace, and the curved form of the flanges g strengthen the bracket at the point where the greatest strain occurs= namely, between the bolt and the neck of the recess engaging the edge of the rail-flange. I have found by experience that these brackets are strong and-durable. I preferably form a recess h in that part of a bracket opposite the rail-flange which forms a ridge is on the top of the bracket above the rail.

1 represents side flanges which abut firmly upon the top base of the rail-flange and forms a seat for the bracket upon the rail. This method of construction enables me to use all the metal from a rectangular blank and sodispose of it in the swaging up of the bracket as to strengthenand support the bent porcontinuous curved flanges, substantially as specified.

2. A tie-bracket for a switch-rail, formed from a rectangular blank and having angular flanges to fit and abut the web and flanges of a rail, and a depending portion forming a hol low shank with continuously-curved flanges extending from the shank to the seat-flanges of the bracket, substantially as specified.

3. A tie-bracket for a switch-rail, formed from a rectangular blank, having vertical and inclined flanges, adapted to fit and seat upon the switch-rail, a recess formed in the neck of the flange adapted to abut the edge of the rail-flange, a vertical hollow shank pierced to receive the tie-bar and continuous curved flanges formed on each side of the shank, substantially as specified.

In testimony whereof I have hereunto set my hand.

CHARLES PARTINGTON.
